TW9984

Intersil has launched a new analogue video decoder with built-in analogue video encoder for around-view parking assist applications.

Based on Intersil’s video decoder technology, the new TW9984 four-channel decoder provides improved safety for drivers and pedestrians and replaces up to nine discrete components with a single chip.

It delivers analogue decoding performance, which gives a good picture quality to generate 360º surround images for advanced driver assistance systems (ADAS).

Motorists will get detailed video from the new TW9984 and can improve their ability to see objects even around the entire vehicle.

"Intersil is a leader in multichannel video and is at the forefront of ADAS around-view camera applications."

Processing video from four cameras, an around-view monitor system collates the four images into a single, birds-eye, top-down view.

With this, drivers will be able to visually confirm the vehicle’s position relative to surrounding objects for easy manoeuvring and parking.

The TW9984 supports four analogue camera inputs simultaneously, as it is integrated with four NTSC/PAL analogue video decoders with ten-bit analog-to-digital converters (ADCs).

It also has a flexible digital output interface, as well as an on-chip analog video encoder that provides the ability to transmit the combined video as a standard analogue composite signal to the head unit display.

On each channel input the decoder also incorporates analogue anti-aliasing filters to further reduce component count.

Intersil precision products senior vice-president Philip Chesley said: "Intersil is a leader in multichannel video and is at the forefront of ADAS around-view camera applications.

"The decoder’s innovative architecture and high level of integration enables an ultra-clear image to increase driver and pedestrian safety, as well as avoid vehicle damage."
